A policy successfully reduces the birth rate, but population growth does not stop immediately. What is a possible reason?

Answer and explanation

Correct answer: Population momentum

The correct answer is A: population momentum. Population momentum means that population can continue to grow for some time even after fertility or birth rates fall. This often happens when a large share of the population is young. As these young people enter reproductive ages, many births may still occur, even if each family has fewer children than before. The effect is delayed because age structure changes gradually, not instantly. B, soil type, may influence agriculture but does not explain this demographic delay. C, a river bend, is a physical feature unrelated to the continuation of births. D is not a meaningful demographic factor. Memory cue: a large young population creates forward motion—lower birth rates may slow growth before they stop it.
